Revitalizing The Great South Bay And The South Shore

We are The South Shore. The Great South Bay is our bay, our heritage and legacy. Through The Creek Defender Program, The I Love Long Island Campaign for bay friendly yards, and our Habitat Restoration Program, and through our strong advocacy, we are fighting for our bay and for the villages that sit on its shores.

Our Mission is to revitalize The Great South Bay so that our children and grandchildren can swim, fish, clam and sail this bay just as those before them had.

Please Contact Us to participate in protecting this legacy.

To Return Our Bay

Together, We Are The South Shore

We are a local 501(c)3 Non-Profit dedicated to revitalizing Great South Bay. We are South Shore residents, past and present, oystermen, fishermen, boaters, surfers, sailors, paddleboarders, environmental advocates, and marine scientists.

Healing Great South Bay is going to take all of us, the many thousands who grew up loving this bay. If we lose our bay, we lose The South Shore and this precious natural gift.  This must not happen on our watch!

We envision one day that the bay, fed by clean fresh water flowing in from its many creeks, will return to its former health. We believe that the investment is worth it, for we are building our own future.

We believe that people will come to understand that restoring nature begins right in their own backyards, and that the chemicals that go on their lawns go into our bay, and even, into our drinking water. We believe that with the right steps to improve water quality, we can help create a $1 billion a year oystering industry, with the oysters themselves helping to filter and clean the bay.

Save Great South Bay’s Facebook group has grown to over 13,000 members. We are in every South Shore town. With our Creek Defender Program, the “Bay Friendly Yards” Pledge and thr Habitat Restoration Program we are set on reviving our bay for today, and for future generations. And there are many ways you can help.

Recent Progress

Here’s what we’ve been up to recently.  Come to our events.   Defend your local creek!  Plant a “swamp forest” of native plants.   Or – if you can’t go in and get dirty yourself, then please donate.   We broke this bay through unmanaged growth and habitat destruction.  We have to fix it.
